Gravitational Lensing : Eddington Experiment

But these results have yet to be proven that gravity waves is what is proven.

Those experts working at the coal face and involved with this momentous experiment, along with other scientists around the world disagree with you.

That coupled with the latest direct evidence of not only the existence of gravitational waves, but also further confirming that which most mainstream reputable cosmologists never doubted, that is the evidence for BH's.
In actual fact it is a ringing confirmation of the nature of BH's and also data that the resultant BH is a Kerr type spinning BH.
And as with all genuine scientific cosmological endeavours, there are other incidents [three or four] that are also being investigated, and the likelyhood of more yet to come.

“Until now, we scientists have only seen warped space-time when it’s calm,” Dr. Thorne said in an email. “It’s as though we had only seen the ocean’s surface on a calm day but had never seen it roiled in a storm, with crashing waves.”

The black holes that LIGO observed created a storm “in which the flow of time speeded, then slowed, then speeded,” he said. “A storm with space bending this way, then that.”
